Power source for single ended tube amplifiers using classical direct hested tubes like 211-845-GM70. for audio amps. This amps get extreme expensive traditional psu. With a low noise smpsu a lot of things gets simpler and much smaller an less expensive. I dream about a high quality supply unit with tabbed filament output 6.3V- 10V-20V I min 25A. and a high voltage output adjustable 1kV - 2kV min. 250mA. Still better the supply should also be able to supply a 300B or other powertube filament 3-5A- 5V and 6.3V and a low plate voltage best tapped to 350V and 450V. Best is if the high voltages rises with some time delay. A supply as described would be an extreme usable power supply for a lot of people building high quality tube amps. It would lower the costs a lot and the weight, too. I know that many tube people would say no no no not smpsu, but the lower costs and the regulation would, I think, far outperform most analog psu used today.
